IST Diving Ear Mask

The mask features a specialized tube and seal system that connects the mask's main lens area to the ear cups. As you exhale through your nose into the mask, air is channeled into the ear cups, equalizing the pressure against your eardrums automatically.

Yes, this mask is compatible with optical prescription lenses. It can accommodate corrective lenses ranging from -1.0 to -8.0 diopters, allowing you to see clearly underwater without needing contacts.

Facial hair can compromise the seal of the ear cups, just as it can with the skirt of a standard dive mask. For the best results, you may need to trim or shave the area where the silicone seal makes contact with your skin to ensure a proper, watertight fit.

By keeping your ears dry and warm throughout the dive, the mask significantly reduces the risk of developing ear infections caused by cold water exposure or contaminated water entering the ear canal.

Because the ear cups keep your ears dry, you may notice a slight difference in how you perceive sound compared to having water directly in your ears. However, many divers find that the design actually improves spatial awareness and makes it easier to localize sounds once they acclimate to the mask.
